Window construction



F. BUTZBACH WINDOW CONSTRUCTION Mayk 12, 1931.

Filed April 15. 1929 v /V i Patented May i i,

PATENT 'oil-#Fica frana Buren, Aor eLIN'roN, Iowa The object a windowconstruction of simple, durable,

and comparatively i.nexpensive manufac-l ture.

More particularly,

head casing has its lower edge provided withv a longitudinal' groovethroughout the i length .thereof and the side casings have upwardlyextending tongues to tit in said.-

groove of the head casing for properly and efficiently aligning the sidecasings with the 'head casin cilitate easy installation of the auxiliaryframe relative to the window frames.

.W ith these and other objects in view my invention` consistsv intheconstruction, arrangement and combination of the various parts of mydevice, whereby the ob'ects contemplated are attained,`as hereina Vermore vfully set forth, ointed outin my claims, and

rail of a storm sash showing the tongue formed thereon. i

0n the accompanying drawings, I have used the reference character A toindicate generally, a window frame. The window frame A includes a sill10, head casing l1:2, l

and side casings 14. The head casing 12 1s provided throughout itslength with a groove 16. The groove 16 is in the lower edge of the headcasing. L

rlhe upper end of each side casing 141, is provided with an upwardlyextending tongue .'18 adapted to tightly tit in the groove 16, wherebythe side casings 14 are conveniently and properly aligned relative tothe head casing 12 when the carpenter is assembling the window frame Ajust before building it into the frame of the building.

In Figures 1 and 5, the brackets a indicate the portions ofthe groove 16into 'which thetongues 18 extend. The bracket b indicates theintermediate portion of the groove adapted to coact with an auxiliaryframe such as a storm sash or window screen frame, as I will nowdescribe.

In Figures 1, 2 and 6, I have illustrated a storm sash B including anupper rail member 20. The rail member 20 is provided throughout itslength with ank upwardly extending tongue 22. The tongue 22 isadapted toposition the frame of the storm sash B relative to the head casing 12,whereby to facilitate installation of the storm sash and to insure theproper alignment of the upperend thereof relative to window frame A.This `makes the jo'b of installing the the tongue 22 on the upper end ofthe sash 'may be caused to enter the portion b of the groove 16 and thenthe lower end of the sash swung inwardly, as indicated Vby the arrows 24.and 26 in Figure 2. 'A

' Thus, while pushing the lower -end n' wardly, the upper end will notfall outwardly, which would make the storm sash obviously hard tohandle. Less hardware can be used with this type of construction. inFigures 1 and 2, I have shown pivoted buttons 28, two of which areprovided adjacent\the lower end of theA storm sash B much simpler andsafer, as

storm sash. Where the groove 16 and tongue 22 are not provided,additional buttons 28 must be provided for the upper end of the stormsash. If desired, the ordinary hinge type of hardware along the upperrail of the sash may also be provided for hanging the sash on and thetongue and groove connection betweenvthe storm sash and the head casingwill facilitate installation of the storm sash even when such hardwareis provided.

Another desirable advantage of my construction is that a betterWind-tight joint is provided between the upper end of the storm sash B-and the head casing 12.

Referring to Figure 4, a window screen C has been illustrated. The upperrail 30 of the screen C is shown formed with 'a groove 32 into which aspline 34 has been glued. The spline 34 acts as a tongue to coact withthe portion Z) of the groove 16 in the head casing 12. In constructingthe storm sash frame or the window screen frame either a tongue may beformed on the upper rail or a spline may be provided, as shown in Figure4. Each construction results in the tongue desired for the purpose ofentering the groove 16.

It will be noted that the inner edge of the spline 34 is slightlybeveled, as indicated at 36 and the tongue 22 is similarly beveled sothat the auxiliary frame may be swung outwardly, as indicated by thearrow 38 before being pulled downwardly, as indicated by the arrow 40without breaking the tongue or spline off. This is necessary also ininstalling the auxiliary frame.

From the foregoing description, it will readily be seen that I haveprovided a window construction in which the tongue and groovearrangement facilitates both the assembly of the window frame and theinstallation of storm sash or window screens.

Some changes may be made in the con'- struction and arrangement of theparts of my device without departing from the real spirit and purpose ofmy invention, and it is my intention to cover by my claims, any modifiedforms of structure or use of mechanical equivalents, which may bereasonably included within their scope.

I claim as my invention:

1. In a window construction, a head casing having its lower edgeprovided with a central longitudinal groove throughout its length. Y,

2. ,In a Window construction, a head casing having its lower edgeprovided with a longitudinal groove throughout its length and side ambseach having a tongue at its upper end to fit into said groove.

3. In a windowconstruction, a head cuasing having its lower edgeprovided with a longitudinal groove throughout its length, side jambseach having a tongue at its upper end to fit into said groove, and anauxiliary frame between said side jambs and having a projecting tonguealong its upper edge to fit in said groove, said tongue and groovepreventing both inward and outward movement of the top of the auxiliaryframe with respect to said head jamb.

4. In a Awindow construction, a pair of side jambs anda head casinghaving its lower edge provided with a longitudinal groove between saidside ambs and an auxiliary frame between said side jambs and having aprojecting tongue along its upper edge to fit in said groove, saidtongue and groove preventing both inward and outward movement of the topof the auxiliary frame with respect to said head jamb.

5. In a window construction, a head casing having its lower edgeprovided with a longitudinal groove and an auxiliary frame having aprojecting tongue along its upper edge to fit in said groove, saidtongue and groove preventing both inward and outward movement of the topof the auxiliary frame with respect to said head amb. y

6. In a window construction, a head casing having its lower edgeprovided with a longitudinal groove, and an auxiliary frame between saidside jambs and having a projecting tongue along its upper edge to fit insaid groove, the inner edge of said tongue being beveled to facilitateentry of the tongue into the groove.

7. In a window construction, a headeasing and an auxiliary frame havinga tongue and groove connection with each other for positioning theauxiliary frame with respect to the head casing and thereafterpreventing both inward and outward movement of the top rail of theauxiliary frame with respect to the head casing.

8. In a window construction, a head casing and an auxiliary frame havinga tongue and groove connection with each other for positioning theauxiliary frame with respect to the head casing and thereafterpreventing both inward and outward movement of the top rail of theauxiliary frame withv respect to the head casing, said tongue having oneedge thereof beveled to facilitate entry of the tongue into the groove.
